Patent number: 8637587Abstract: Release agents with increased affinity toward nano-imprint lithography template surfaces interact strongly with the template during separation of the template from the solidified resist in a nano-imprint lithography process. The strong interaction between the surfactant and the template surface reduces the amount of surfactant pulled off the template surface during separation of a patterned layer from the template in an imprint lithography cycle. Maintaining more surfactant associated with the surface of the template after the separation of the patterned layer from the template may reduce the amount of surfactant needed in a liquid resist to achieve suitable release of the solidified resist from the template during an imprint lithography process. Strong association of the release agent with the surface of the template facilitates the formation of ultra-thin residual layers and dense fine features in nano-imprint lithography.Type: GrantFiled: September 7, 2011Date of Patent: January 28, 2014Assignee: Molecular Imprints, Inc.Inventors: Frank Y.

The curable solid ink composition has a viscosity in the range of less than 10 cPs at 90° C., a shrinkage value of less than 3%, and a superior curing rate compared to existing curable solid ink compositions. The ethoxylated octylphenol derivatives may be prepared by reacting an ethoxylated octylphenol, a linear alcohol, and diisocyanates or polyisocyanates.Type: GrantFiled: February 11, 2010Date of Patent: August 7, 2012Assignee: Xerox CorporationInventors: Marcel P. Breton, Michelle N. Chretien, Jeffrey H. Banning, Stephan V. Drappel, Ian R. Duffy, Christopher A. Wagner

Patent number: 8222313Abstract: Radiation curable compositions, such as UV curable ink compositions, contain a polymeric dispersant, a curable material, that includes a carrier and at least one nanoscale fluorescent pigment particle and an optional non-fluorescent colorant. The fluorescent organic nanoparticle composition includes one or more fluorescent dyes dispersed in a polymeric matrix obtained by modified EA latex process or by emulsion polymerization. In a different embodiment, the nanoscale fluorescent pigment particle composition includes pigment molecules with at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, the functional moiety of the pigment associates non-covalently with the functional group of the stabilizer, and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized pigment particles.Type: GrantFiled: October 6, 2008Date of Patent: July 17, 2012Assignee: Xerox CorporationInventors: Gabriel Iftime, C.

Patent number: 8211508Abstract: A process for producing a molded printed material is provided that includes (A) a step of forming an image by discharging an ink composition on a support by an inkjet method, the ink composition comprising at least 60 wt % relative to the entire ink composition of at least one monofunctional radically polymerizable monomer having only one unsaturated double bond group selected from the group consisting of an acrylate group, a methacrylate group, an acrylamide group, a methacrylamide group, and an N-vinyl group and having at least one cyclic structure-containing group, (B) a step of curing the ink composition by irradiating with actinic radiation the image obtained so as to obtain a printed material having the image cured on the support, and (C) a step of molding the printed material. There is also provided a molded printed material obtained by the process for producing a molded printed material.Type: GrantFiled: September 24, 2007Date of Patent: July 3, 2012Assignee: FUJIFILM CorporationInventor: Yuuichi Hayata

Patent number: 8207240Abstract: A method to reduce or minimize the reduction in molecular weight of a stent during processing is disclosed. The stent has a scaffolding including a polymer formulation comprising PLLA and polymandelide. The polymandelide reduces the molecular weight drop during processing, particularly during sterilization. The stent scaffolding can further include one or more additional stabilizing agents that additionally reduce the molecular weight drop during processing.Type: GrantFiled: September 14, 2009Date of Patent: June 26, 2012Assignee: Abbott Cardiovascular Systems IncInventors: Byron Lambert, Yunbing Wang, James Oberhauser
